Privacy Policy

Last updated: 2026-07-24

QRBarcodeTools is built to protect your privacy. This policy explains what happens to your information when you use our tools.

Processing in your browser

All QR code and barcode generation, and all scanning, happens locally in your browser using JavaScript. The content you enter — URLs, Wi-Fi passwords, contact details, emails, phone numbers, SMS text, locations, calendar events, barcode numbers, uploaded images and generated code images — is never sent to our servers.

No uploads

Images you upload to add a logo or to scan are read into your browser's memory only and are not transmitted anywhere. They're released from memory when you remove them or leave the page.

Camera access

The scanner requests camera access only when you press the start button. Video frames are analyzed on your device and never uploaded, and the camera is fully released when you stop scanning or leave the page.

Local storage

We use your browser's local storage only for convenience settings such as your light/dark theme preference and a short list of recently used tools. We never store Wi-Fi passwords or other sensitive data you enter into the generators.

Analytics

We use Google Analytics 4 (measurement ID G-X3K5GN4PJ4) to understand which pages are visited and how many people use the site. It sets cookies in your browser and collects standard measurement data such as the page you viewed, an approximate location derived from your IP address, your device and browser type, and a randomly generated identifier. This data goes to Google as a third-party processor; see Google's privacy policy.

What analytics never sees: the content you type into any generator. We send no custom events, no form values and no URL parameters containing your data, and everything you encode stays in your browser. Analytics measures page views only.

You can opt out with the Google Analytics opt-out browser add-on, by blocking cookies for this site, or by using a browser or extension that blocks tracking scripts. The tools work exactly the same either way.

Advertising

The site does not currently serve ads. If advertising (such as Google AdSense) is added in future, it will be disclosed here, and we will ensure the data you encode is never passed to those systems through events, URL parameters, logs or error reports.

Third-party libraries

We use open-source libraries (for QR generation, barcode rendering and code scanning) that run in your browser. They do not send your data to third parties.

Your rights

Because we don't collect personal data, there's nothing for us to access, correct or delete on your behalf. You can clear your browser's local storage at any time to remove saved preferences.

Children's privacy

Our tools are general-purpose utilities and are not directed at children. We do not knowingly collect any personal information from anyone, including children.

Changes to this policy

We may update this policy as the site evolves. Material changes will be reflected by the "last updated" date above.
